Bilateral Hearing Loss Clinical Trial
Official title:
Pilot Study of the Feasibility and Efficacy of Working Memory Training in Children With Cochlear Implants
This study is an investigation of the effect of a computer-based working memory training program on memory and language processing in at-risk children (e.g., those with working memory weaknesses) who have received cochlear implants.
The long-term goal of this research program is to improve speech-language outcomes in
prelingually deaf children who receive CIs. The objective of this proposal is to investigate
the short-term effects of a novel working memory training program on memory, learning, and
speech-language outcomes in children with CIs. The specific hypothesis of this project is
that completion of a behaviorally-based training program designed to increase working memory
capacity will improve attention, working memory span, and working memory-related
speech-language processing in a group of deaf children with CIs. This hypothesis is based on
past research demonstrating the efficacy of working memory training programs in improving
attention and working memory in children with attention deficits, as well as on past
research showing an association between working memory and speech-language outcomes in
children with CIs. Knowledge about the effects of working memory training on CI
speech-language outcomes will provide a better understanding of the process by which
children with CIs learn speech-language following implantation and may offer an entirely new
avenue of intervention to improve speech-language outcomes, particularly in deaf children
who show limited improvement following implantation.
The specific aims of this study are:
1. Specific Aim 1: Determine the feasibility and application of a novel, computer-based
working memory training program when applied to children with CIs. We hypothesize that
children with CIs will show a progression of learning in both auditory and visual
working memory during the training program that will mirror that of normal-hearing
children.
2. Specific Aim 2: Determine the effect of the working memory training program on core
attention, concentration, and working memory processes of children with CIs. We
hypothesize that children with CIs will show improvement on both laboratory-based and
parent-report measures of attention, concentration, and working memory processes after
working memory training, compared to a baseline period.
3. Specific Aim 3: Determine the effect of the working memory training program on working
memory-related speech-language outcome measures in children with CIs. We hypothesize
that children with CIs will show improvement on auditory working memory, verbal naming
fluency, and word repetition after training.
